DS1624 8-PIN DIP (300 MIL)

See Mech Drawings Section

§ 8-pin DIP or SOIC packages

SCL - 2-Wire Serial Clock

GND - Ground

- Chip Address Input

V_DD- Digital Power Supply (+3V - +5V)

NC - No Connection

DESCRIPTION

The DS1624 consists of a digital thermometer and 256 bytes of E²memory. The thermometer provides

13-bit temperature readings which indicate the temperature of the device. The E²memory allows a user to

store frequency compensation coefficients for digital correction of crystal frequency due to temperature.

Any other type of information may also reside in this user space.
